With Right Move, Tepilo, Zoopla, Up my street or Find a property, we are a nosey bunch in the UK. If we aren’t buying property, we love to know what Mrs Jones paid for hers down the road. Or what the neighbours house looks like on an estate agents site. 10 Downing Street, colloquially known in the United Kingdom as “Number 10”, is the headquarters of Her Majesty’s Government and the official residence and office of the First Lord of the Treasury, an office now invariably held by the Prime Minister.

Just imagine if 10 Downing Street was for sale

So what if 10 Downing Street was for sale? well we know its not that simple if you want to move into that address and it certainly isn’t based on price alone. Though imagine for a moment if it was a simple as an asking price…

Zoopla recently valued the residential portion of 10 Downing Street, worked out under which PM value was lost and gained, calculated the stamp duty payable in April 2011 (at 5%, that’s £225K) if it was for sale on the open market, and identified and worked out the value of other 10 Downing Streets around the UK.

Here are their reported results for 10 Downing Street:

Gordon Brown currently worth a £4,574,831

Tony Blair when he left was worth £5,037,251

John Major £1,644,558

Margaret Thatcher £1,804,952

Zoopla also reports that property prices have risen since the last election in 2005 in each of the party leaders’ constituencies

by over 12% in David Cameron’s;

by just over 5% in Nick Clegg’s

by almost 19% in Gordon Brown’s

So there you have it, thanks to Zoopla we now know it’s not been the best property boom in recent times, which of course we knew already.
